Carbon supported Pt-Sn nanoparticles as anode catalyst for direct borohydride-hydrogen peroxide fuel cell: Electrocatalysis and fuel cell performance

► The Pt-Sn/C electrocatalysts were synthesized by a modified NaBH4 reduction method. ► The average particle size of Pt-Sn nanoparticles is approximately 3 nm. ► The Sn-doping can apparently improve the electrocatalytic activity for the BH4− electrooxidation. ► The performance of DBHFC employing Pt-Sn/C as anode catalyst was reported. ► The maximum power density as high as 91.5 mW cm−2 was obtained at 25 °C.
